The output says that description for newly added field is missing.
I think adding some description like

* @fasync_readers: reader side fasync
* @fasync_writers: writer side fasync
* @bufs: the circular array of pipe buffers
+ * @user: the user who created this pipe
struct pipe_inode_info {
struct mutex mutex;

will fix.
